Copying a chart to the clipboard?

[tonyvsuk]

Hello,

I'm trying to get a bitmap of my chart onto the clipboard, but struggling to do so (I keep getting an invalid bitmap message).

Has anyone else succeeded?

My code is below. I've tried two different ways to get at the data (pBMPData below), neither worked for me.

Thanks in advance,

Tony.

if (wxTheClipboard->Open())
{
	BaseChart *pChart = getChart();

	if (pChart != NULL)
	{
		MemBlock block = pChart->makeChart(Chart::BMP);

		//size_t buflen = block.len - sizeof(BITMAPFILEHEADER);

		const char *pBMPData = block.data;
		//const char *pBMPData = (block.data + sizeof(BITMAPFILEHEADER));

		wxBitmap bmp(pBMPData);
		wxBitmapDataObject *pBMPObject = new wxBitmapDataObject(bmp);

		wxTheClipboard->SetData(pBMPObject);

		wxTheClipboard->Close();
	}
}

Unfortunately, the memory block returned by makeChart(Chart::BMP) can't be passed directly to a wxBitmap constructor. First, you have to convert the memory block to a wxImage object that then can be passed to a wxBitmap constructor.

The code looks like this:

  MemBlock block = c->makeChart(Chart::BMP);
  wxMemoryInputStream in(block.data, block.len);
  wxBitmap bmp(wxImage(in, wxBITMAP_TYPE_BMP));
